WATCH-BOW FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 414,828, dated November12, 1889.

Application filed July 13, 1889. Serial No. 317,377. (No model.)

To all whom it may concern.-

Be it known that I, FRED L. TURNER, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inVVatch-Bows, of which the following is a specification.

My invention has reference to watch-bows; and it consists of certainimprovements, which are fully set forth in the following specificationand shown in the accompanying drawings, which form a part thereof.

It has been proposed to provide a watchpendant with a bow hinged to itand positively held thereto by a tubular-lockin g piece which fits intothe pendant, and is formed with slots or notches adapted to encircle theends of the bow and constructed to fit into the annular grooves formedthereon. This is clearly set out in Letters Patent No. 300,700, datedJune 17 1884, to David Glickman.

My invention is an improvement upon the structure set out in thatpatent; and it consists in forming the tubular locking-piece withscrew-threads, whereby it may adjustably be secured to the pendant andadapted to put any degree of friction on the bow, so that it shall notbe too loosely connected to the pendant.

In the drawings, Figure 1 is a sectional elevation of a watch pendantand bow embodying my invention. Fig. 2 is an elevation of thelocking-piece removed, and Fig. is a plan View of same.

A is the pendant, and is provided with the holes 13, arrangeddiametrically opposite for the ends of the bows O, and is alsointernally screw-threaded at its top or upper part, as shown at F. Thehow 0 is journaled in the holes or sockets B, and its ends are formed 40with annular grooves c to form heads upon the ends. These heads may beformed in any other way desired.

D is the ann ular'looking-sleeve, and has a smooth lower part d, adaptedto fit into the annular grooves c of the bow, and a screwthreaded upperpart, as at E, which is de signed to screw into the threads F in thependant. This locking-sleeve may have notches Gwhereby it can be screwedin or out by the proper tool.

It is quite evident that the annular grooves 0 need not extend all theway around the ends of the bow, as said bow cannot make a completerevolution on the pendant.

It will now be understood that after the bow has been snapped in placeon the pendant the annular sleeve D may be screwed down so that its edge(I fits into the grooves c of the bow, and, owing to the fact thatthesleeve D has no notches or slots to [it around the ends of the bow,there is nothing to prevent such adjustment as may be desired to varythe friction due to the pressure of the part at upon the ends of thebow. By making the pitch of the screw-threads small there is no tendencyof the sleeve D to work loose; and it is also to be borne in mind thatany action of one end of the bow on the sleeve D to rotate it iscounteracted by a similar action by the other end of the bow, thuspreventing the movement of the bow inducing any tendency to looseness.

Having now described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

l. The combination of a watch-case pendant, a bow journaled therein andhaving its ends extended within the pendant and form ed with heads, andan annular locking-sleeve screwed into the pendant and having its endextending back of the heads of the bow ends.

2. The combination of a watch-case pendant, a bow journaled therein andhaving its ends extended within the pendant and form ed with heads, andan annular locking-sleeve screwed into the pendant and having its endmade smooth and extending back of the heads of the bow ends.

3. The combination of a pendant, a bow j ournaled therein and having itsends formed with grooves, and an adj ustable locking-sleeve made annularand screwed into the pendant and having its lower edge extending intothe grooves of the bow.

t. The combination of a pendant, a bow journaled therein and having anend formed with a head, and a rotatable and adjustable annular sleevecontained within the pendant, having a continuous lower edge fittingback of said head and permitting rotation of both the bow and thesleeve.

In testimony of which invention I have hereunto set my hand.

FRED L. TURNER.
